FIGURE 128. Range map of Apodemus peninsulae in Korea. Range: The Korean field mouse commonly occurs throughout Korea , except in remote islands ( Fig. 128 ). Remarks: Due to morphological differences such as the number of mammae, skull, and teeth, Jones (1956) promoted peninsulae to a distinct species. The presence of three region-specific mtDNA types of ancient divergence likely resulted from the regions of Primorye, Siberia and the Korean Peninsula functioning as refugia for A. peninsulae during a substantial period of the Quaternary glacial ages ( Serizawa et al . 2002 ). According to a phylogenetic study based on cytochrome b , the Korean population is closer to populations from Shandong and Ningxia , China than from those of the Russian Far East ( Sakka et al. 2010 ). A numerical taxonomy and genetic study suggests the occurrence of two subspecies ( A. p. peninsulae and A. p. sowerbyi ) in Korea (Heo 2002) .
